摘要:
The present invention comprises a closed-loop filter system for continuously removing a metal hydroxide precipitate from an alkali metal hydroxide solution. The filter system comprises a filter having a filter surface and a plurality of small diameter openings in said surface. The alkali metal hydroxide solution is impacted onto said filter surface, metal hydroxide precipitate agglomerating on said surface. The filter surface openings have an average diameter effective for said agglomerating. Means are provided to remove the agglomerated precipitate from said filter surface, and to separate the agglomerated precipitate from the alkali metal hydroxide solution, the agglomerated precipitate having a particle weight to surface area ratio effective for said separation.
